White House reacts to McClellan's book

From NBC's Les KretmanWhite House press secretary Dana Perino released this statement on Scott McClellan's critical book on the Bush White House:

"Scott, we now know, is disgruntled about his experience at the White House. For those of us who fully supported him, before, during and after he was press secretary, we are puzzled. It is sad -- this is not the Scott we knew."

More from Perino: "The book, as reported by the press, has been described to the president. I do not expect a comment from him on it -- he has more pressing matters than to spend time commenting on books by former staffers."
